Plants absorb CO2, turn it into oxygen and spread this into the air. That is why we have placed big plants in our care centers. When the air is of good quality people are more active and it helps them to sleep deeper and better. We have also placed daylight lamps in certain parts of our care center. Day light is very important for our biorhythm. It stimulates all kind of processes in our body and helps to sleep better. A lack of day light can disturb our biorhythm and it can have a negative effect on people’s mood and can even result in a depression.
